Best Practices

1. Always Document Parameters

{% comment %}
  Parameters:
  - param {type} - Description [required/optional]
{% endcomment %}

2. Provide Defaults

{%- liquid
  assign show_vendor = show_vendor | default: false
  assign image_size = image_size | default: 400
-%}

3. Validate Required Parameters

{%- if product == blank -%}
  <p class="error">Product parameter is required</p>
  {%- return -%}
{%- endif -%}

4. Handle Empty States

{%- if image != blank -%}
  <!-- Image markup -->
{%- else -%}
  <div class="placeholder">No image available</div>
{%- endif -%}

5. Escape User-Provided Content

<h3>{{ product.title | escape }}</h3>
<p>{{ customer.name | escape }}</p>

6. Use Semantic HTML

<article>  {%- # For products -%}
<nav>      {%- # For navigation -%}
<aside>    {%- # For sidebars -%}
<section>  {%- # For content sections -%}

7. Include Accessibility Attributes

<button aria-label="Add {{ product.title | escape }} to cart">
  Add to Cart
</button>

<img src="..." alt="{{ image.alt | escape }}">

<div role="status" aria-live="polite">
  Item added to cart
</div>
